Ronit Kreisberger QC

Monckton Chambers

Highly in demand, with a jam-packed diary right up to the end of 2022, Ronit Kreisberger QC is spearheading heavyweight competition litigation at Monckton Chambers.

She is at the heart of the collective actions trend, acting on several high-profile cases at the CAT. Hot on the heels of Merrick v Mastercard, she acted in Justin Le Patoure v BT. The £600m claim against BT alleged excessive pricing in abuse of its dominant position in stand-alone landline telephone services. In 2021, she represented the claimants in a £1.5bn collective action case against Apple. The tech giant has allegedly been overcharging customers of its App Store.

This is Kreisberger’s second time in the Hot 100, having made the list in 2007 when she was just two years’ call. Then, she acted in the first case in which a UK court awarded damages for harm suffered because of a competition law infringement.

There is no sign of her slowing down any time soon, as she kicks off this year with a case very similar to the Apple one, this time against Google.
